Abstract
Abstract A tilt and height adjustable display stand has a display mechanism connected to a base through a series of interconnecting linkage arms. A tilt gas spring and a height gas spring are interconnected within the linkage in such a manner as to offset the weight of the display mechanism when the display mechanism is tilted or moved vertically.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
89 words
A tilt adjustable display stand comprising: (a) base means; (b) display means; (c) linkage means, connecting the base means to the display means, the linkage means including a tilt housing connected to support the display means and a support housing to which the tilt housing is pivotally attached; and (d) a tilt gas spring, connected to the tilt housing at one end and to the support housing at the other end, positioned to counterbalance the weight of the display means to enable low force tilting of the display means.
Claim 2
Dependent Claim
89 words
A tilt adjustable display stand comprising: (a) base means; (b) display means; (c) linkage means, connecting the base means to the display means, the linkage means including a tilt housing connected to support the display means and a support housing to which the tilt housing is pivotally attached; and (d) a tilt gas spring, connected to the tilt housing at one end and to the support housing at the other end, positioned to counterbalance the weight of the display means to enable low force tilting of the display means.
